San Francisco is a city of steep hills and tight lots, where a roof is less a surface than a battle line against salt air, marine fog, and atmospheric-river storms. From the Victorians of Pacific Heights and the Haight to the stucco row houses of the Sunset and Richmond, the building stock here was never designed for the wind-driven rain that rolls in off the Pacific. That is why Metal Roof Installation in San Francisco has become the go-to answer for homeowners who are done replacing shingles every 15 years. We install panel systems over premium synthetic underlayment with proper ventilation, flashing, and manufacturer-certified details for a 40 to 60 year service life. Since 2009 we have worked the hills from Twin Peaks to Bernal Heights, and we know what the fog does to fasteners and what a Pacific storm does to a poorly flashed chimney. If you are weighing your options, start with our standing seam metal roofing page to see the system most San Francisco homeowners choose.
Why Metal Roof Installation Matters on San Francisco's Foggy, Salt-Air Hills
The dominant failure mode in this city is not snow load or hail. It is wind-driven rain pushing under shingle courses and salt-air corrosion eating fasteners and flashing on homes within a mile of the ocean. Add the constant fog drip on the west side and the redwood and eucalyptus debris in the Oakland and Berkeley Hills, and asphalt shingles here are lucky to see 20 years. Metal panels shed water fast, resist corrosion when specified correctly, and do not rot, crack, or grow moss.
- Standing seam panels handle the atmospheric-river storms that dump inches of rain in hours without lifting or leaking.
- Coastal-rated finishes resist the salt air that pits cheap fasteners within a decade in the Sunset and Richmond.
- Metal sheds redwood needles and cypress debris that trap moisture and rot shingle roofs in Marin and the hills.
- Panels weigh far less than tile, which matters on the steep hillside homes stepping up Twin Peaks and Diamond Heights.
- A properly vented metal roof cuts attic heat gain and keeps the Victorian top floor livable in September.
For homes in historic districts, we match panel profiles and colors to the neighborhood so the roof reads as an upgrade, not an eyesore.
Key info: A 1920s Spanish Revival in the Marina with original clay tile can often take a stone-coated steel panel that matches the tile profile and cuts the roof weight by more than half. We see this conversion regularly in St. Francis Wood and Forest Hill.
Before any contract is signed, check the City and County of San Francisco permit resources so you understand what your jurisdiction requires for a re-roof.
How We Install a Metal Roof on a San Francisco Home
Every installation starts with a tear-off and a deck inspection, because we will not cover a soft or rotted substrate. On these 1880s to 1950s homes we routinely find skipped sheathing, old skip-sheathing boards, and water damage behind parapets that the last roofer hid. We correct the deck, then build the roof from the underlayment up. The sequence below is the same whether we are on a flat-roof Sunset row house or a steep gable in Noe Valley.
- We pull the permit and confirm historic district or HOA design review requirements before ordering material.
- We remove the old roofing and inspect the deck, replacing any soft or delaminated sheathing.
- We install premium synthetic underlayment and ice-and-water shield in the valleys and around penetrations.
- We set the panels, align the seams, and fasten to manufacturer specification for wind uplift.
- We fabricate and install flashing at chimneys, skylights, walls, and parapets, then seal every penetration.
- We verify attic ventilation and install the ridge vent or balanced intake and exhaust.
- We walk the roof with you, hand over the manufacturer warranty, and clean the gutters and site.
If your home already has one layer of shingles and the deck is sound, a metal roof over shingles retrofit can save the tear-off cost and a day of labor.
Key info: On a Noe Valley Victorian with a hidden flat roof behind a false front, we installed a standing seam system with a custom parapet flashing. The homeowner had been chasing a leak at the cornice for three winters. The new flashing and panel system ended it in one dry season.
Metal Roof Installation Methods We Use in San Francisco
The right system depends on your roof pitch, your budget, and how visible the roof is from the street. A low-slope flat roof in the Sunset takes a different panel than a steep Victorian gable in the Haight. Here is how the main approaches compare.
| Approach | Description | Best for |
|---|---|---|
| Standing seam | Concealed fasteners, raised seams, clean vertical lines, 40 to 60 year life | Modern infill, steep gables, homeowners who want the longest service life |
| Exposed-fastener corrugated or ribbed panel | Through-fastened panels, lower material cost, fast install | Budget-conscious re-roofs, sheds, garages, commercial and agricultural buildings |
| Stone-coated steel | Steel core with a stone granule finish that mimics tile or shake | Spanish Revival and Mediterranean homes in the Marina and St. Francis Wood |
| Metal shingle | Interlocking panels stamped to look like slate or wood shake | Historic districts and HOA communities with design review |
| Copper and specialty metal | Soldered seams, natural patina, premium architectural finish | Landmark homes, bay windows, and homeowners who want a forever roof |
We will tell you straight which system fits your pitch and your block, and we will not upsell a standing seam onto a shed that a ribbed panel handles fine.
Metal Roof Installation Cost in San Francisco: What to Expect
Pricing starts from $8 per square foot for a basic exposed-fastener installation on a straightforward roof. Real jobs in this city land higher, because access is rarely straightforward. A steep hillside home in Bernal Heights, a three-story Victorian with a narrow side yard in the Mission, or a Pacific Heights roof behind a parapet all add labor. Material choice is the other big lever: standing seam and copper sit well above a ribbed panel. Getting two or three written estimates is the smartest move, because scope varies wildly and a low bid often hides a thin underlayment or skipped deck repair. Our full pricing overview breaks down the ranges by system.
Ask every contractor whether the price includes the permit, the tear-off, deck repair, and flashing. Those line items are where budgets blow up.
What to Look for When Hiring a Metal Roofing Contractor Near San Francisco
This is a licensed trade and a long-lived purchase, so vet the contractor before you talk color swatches. California requires a valid contractor license, and you can verify it through the state board. Ask for a certificate of insurance, and confirm the crew carries workers' compensation, because a roofer who falls on your property without coverage is your problem. Call two recent references in your neighborhood, ideally on a home with a similar roof pitch and access.
- Confirm the license is active and the insurance certificate names general liability and workers' comp.
- Get two or three written estimates that list materials, underlayment, flashing, and permit fees.
- Ask who pulls the permit, because the homeowner should not be the one signing for the contractor's work.
- Check whether historic district or HOA design review applies to your block before you order panels.
- Read the manufacturer warranty and confirm the installer is certified to offer it.
